Hot dip galvanized is an effective way of metal corrosion, mainly used for metal structure on the facilities, railway and so on. It is take steel parts after rust removal immersed in the molten zinc solution at about 500 degrees, make the steel surface is attached to the zinc layer, so have the purpose of anti corrosion.  Hot dip galvanized process is completed by the more ancient hot plating method development, it has been more than 160 years since, in recent years, it has been developed on a large scale. Zhongbo supply quality  Hot Dip Galvanized Track Bolt ,  Bridge Bolt  for the rail way. 

Railway Fastening System   refers to a group of mechanical parts used in general to fasten two or more parts (or components) which need to be connected together as a whole when . A wide range of fasteners are found on various machines, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, meters and supplies. Fasteners are characterized by a wide range of specifications, performance,  different usage, and standardization, serialization, universal species is also in a very high level. Fasteners are the most widely used mechanical foundation. Railway fasteners  are widely used in urban rail construction. In recent years, railway fasteners have emerged in the field of railways and steel structures, and have won praise from many people in the industry and consumers. Railway fasteners play a crucial role in the railway.  Railway joints  are the most fundamental cause of vibration; if we want to avoid the emergence of th...

When the mechanical components are installed on the concrete foundation, the J shaped, L shaped end of the  Track Bolt  is embedded into the concrete. Anchor Bolt  tensile strength is the tensile capacity of the round steel itself. The size is equal to the sectional area multiplied by the allowable stress value, which is the allowable tensile bearing capacity of the design. The anchor bolts are usually made of Q235 steel, that is light circle. Q345 strength is big. For circular anchor bolt, the buried depth is usually 25 times the diameter of the bolt, then a 90 degree crooked hook with a length of 120mm or so. Both the buried depth and the crooked hook are to ensure the friction of the bolt and the foundation, so that the bolt will not be pulled out.

1.Double head bolts need to be installed on the main body of equipment, view mirror, the mechanical seal seat double head bolt, the deceleration frame and so on. At this time, double head bolts are used, on end is screwed into the main body, the attachment is attached to the other end. Because the attachment is often dismantled, the thread will wear or damage, it will be convenient to replace it with double head bolts. 2.The thickness of the connecting body is large, and the bolt is used when the length of the bolt is long. 3.For connecting thick plate and inconvenient use of  Hex Bolt  connection, like concrete roof, roof beam hanging monorail pendant and so on. In addition, we also supply other  Railway Fastening  with best price.
